Français : Following the experience on MuSCAT, we adopt commercially-available

g ′ , r ′ , and z s

band filters of Astrodon Photometrics Generation 2 Sloan filters for ch. 1, 2, and 4, respectively. The three filters are the same with those for MuSCAT on Okayama 1.88-m telescope. On the other hand, since the 

i ′

band filter of Astrodon Photometrics Generation 2 Sloan filters has an unavoidable overlap of transparent wavelength with the 

r ′

and 

z s

band filters, we adopt a custom-ordered 

i

band filter manufactured by Asahi Spectra Co., Ltd. For simplicity, hereafter we call those channels as 

g , r , i , and z s

bands, respectively. We note that the reflectance and transmittance of the DMs are optimized for those four bandpass filters. The size of those filters is 

50 mm × 50 mm

. Figure 6 plots the measured transmittance of the bandpass filters.
